How could I overcome tensorflow-gpu import error?

I'm new tensorflow programming. We have RTX2080 TI GPU in the workstation.
Win 10 64 bit OS installed on it. I'm using Pycharm Community Edition 3.1 edıtor

I researched from the net(also from this similar questions) and I set up following versions below:

Cuda 10.00
Cudnn v7.6.2.24
Python 3.6
Tensorflow-gpu 1.14.0

Unfortunately when I run this command:

import tensorflow as tf

Pycharm gave this error into the python console:

How could I overcome these errors? Which versions of Phyton, Cuda,cuDNN, tensorflow-gpu are compatible with each other?

Would you give me advices please??

Have you used the command prompt in administrator mode?

Use the below command:

pip3 install --upgrade tensorflow-gpu

I solved my problem just as:

Set up tensorflow -gpu 1.5

after downgrade protobuf 3.6.0 just as:

 pip install protobuf==3.6.0

İt worked!!
